Polybriks
Transforming plastic waste into durable and affordable construction materials as we tackle climate change.
Waste plastic is collected from within the communities and recycled to manufacture Polybriks, tiles, ceiling, among other construction materials.
The waste plastic is fixed into durable materials that will be locked up in permanent constructions that will last for centuries. The plastic in the product or building will not be accessible for recycling into transitory products.
Relatively large amounts of collected plastic will be molded into individual products which will act as trusted plastic reservoirs. This is a solution to plastic pollution.
Processes involved in the solution include;
Collecting and sorting of the different plastic wastes. This involves GPS readers equipped on every trash bin.
Shredding of the plastic using plastic shredder machine
Molding of plastic into products using 3D printing technology and traditional technology of human-developed molders and architecture technology.
Plastic pollution.
In Kampala and Uganda at large, plastic usage has been increasing over the past decades and these plastic products are less durable. This resulted in a surge in plastic waste disposal in the communities. Up to 600 metric tons of plastic waste a day (2021). Attempts have been made to tackle the problem but only about 6.1% of the waste is collected for recycling.
Citizens living in the suburbs of Kampala (app. 3,100,000) are the most affected especially when the disposed of plastic blocks the drainage systems of the area.
The problem is escalated by; -
the improper disposal of plastic waste by household individuals. At most times, citizens dispose of the plastics together with bio-wastes into their land farms.
the rise of usage of single-use plastics.
recycling waste products into transitory non-durable products for reuse by the citizens. This increases the chance of that very plastic being poorly disposed of in a short time.
Plastics blocks drainage channels thus resulting in frequent flooding, burning of plastic waste as a way of reducing their volumes in households results in the release of toxic gases responsible for respiratory issues, plastic wastes in Lakes are consumed by fish, waste plastics harbor disease vectors such as mosquitoes which threatens the people's lives.
Globally, waste plastic contributes to climate change. both through direct release of greenhouse gases when heated and indirectly by negatively affecting aquatic organisms.
Public. These are the general people within the communities regardless of gender, education level, age, religion in the area where the solution is being implemented.
The creation of plastic waste-free communities will positively change people’s behavior towards plastic waste disposal. The solution will eliminate waste disposal sites that act as breeding sites of various disease vectors such as mosquitos, houseflies.
The solution provides durable affordable construction materials for community critical facilities such as hospitals, schools, etc.
Youth. This includes individuals within the 16-30 age group, both males and females that are able to participate in the solution’s activities. The youths in Uganda constitute 77% of the total population with over 7.3 million people.
In Uganda, unemployment is the main challenge faced by the youth, with an estimated rate of 2.48% and this can be anticipated as the main source of other challenges.
Youths cannot afford to own housing because the durable construction materials available in the country are costly. Again, there is a deficit of residential housings for the youths in the country since the construction materials are costly.
The solution will create employment opportunities for people at all stages of execution from plastic collection to selling of construction products. This will improve their income levels to sustain their basic needs.
Affordable durable construction materials will enable the construction of affordable residential facilities in urban areas to serve the increasing residential demands of the youth in urban centers
Our team conducted a survey where we mainly used scientific observation to understand the rate of plastic pollution within the communities. it was observed that in every 15 strides within the suburbs, at least 3-5 plastic bottles were randomly distributed within the area.
We interacted with some household individuals about the various ways they undertake to dispose plastic wastes. Research showed that most of the individual used burning to eliminate the plastics, a few of the individuals collected the plastics in bags "obukutiya" [lug.], to be collected by waste collection companies such as Nabugabo Up Deal Venture. few member were observed to practice backyard farming of vegetable crops using plastic wastes but these were also limited to buckets.
We made study visits to some of the recycling companies of Uganda for example Ecobrix, up cycle Uganda. They faced a challenge of collecting wastes that consisted of plastics and organic wastes, this made sorting difficult.
The above made us understand that people need a plastic-free environment.
But this meant dispose of plastics in an eco-friendly format. This intrigued us to think of recycling the wastes into durable plastics that will last for years, the Polybriks. The congestion in the suburbs was an indicator for people's demand for affordable residential housing.
This required production of construction materials that don't require sand, cement, lime in order to down play the expenditure that people usually have to consider before construction in Uganda.
- Taking action to combat climate change and its impacts (Sustainability)
- Concept: An idea being explored for its feasibility to build a product, service, or business model based on that idea
We have accumulated enough required knowledge from our research, with engagement of various target users of the solution.
To date, we have validated the idea, and we are set to realize it provided that the key resources for the business are available to us.
- A new use of an existing technology (e.g. application to a new problem or in a new location)
The solution involves the use of 3D printing machines to manufacture the bricks, pavers, tiles ceiling among others. The bricks and pavers will have perfect dimensions with interlocking characteristics that shall enable binding of bricks.
The technology in this solution enables the construction of housing for example a bungalow without running into the costs of cement, sand, etc. used to make mortar for binding the bricks together most especially when partitioning the rooms, let say; dining room, bedrooms, kitchen room, among others. This makes the construction of one’s house affordable. (sand-less and cement-less strong walls)
This shall limit wastage of resources and also minimize the wastes from the construction industry
The technology ensures the completion of a building in the shortest time possible compared to the local earth bricks.
The solution involves the use of Global Position System (GPS) trackers which will be placed on plastic collection bins available in the communities. These will provide more relevant information on the places that have more plastic waste disposal so that they can be collected. In Kampala and Uganda at large, the collection centers flood with wastes because of the delay in collecting the wastes.
- GIS and Geospatial Technology
- Imaging and Sensor Technology
- Manufacturing Technology
- Materials Science
- Uganda
The solution is projected to impact 4.5 million people in Uganda in the next year. This includes people that will directly get employment opportunities from the solution implementation, potential buyers of the products and the beneficiaries of the services attached such as plastic-free community, environmental education among others.
